A coated steel substrate including a coating including nanographite having a lateral size between 1 and 60 μm and a binder, wherein the steel substrate has the following compositions in weight percent: 0.31≤C≤1.2%, 0.1≤Si≤1.7%, 0.7≤Mn≤3.0%, P≤0.01%, S≤0.1%, Cr≤0.5%, Ni≤0.5%, Mo≤0.1%, and on a purely optional basis, one or more elements such as Nb≤0.05%, B≤0.003%, Ti≤0.06%, Cu≤0.1%, Co≤0.1%, N≤0.01%, V≤0.05%, the remainder of the composition being made of iron and inevitable impurities resulting from the elaboration; and a method for the manufacture of the coated steel substrate.

Coated steel substrate

A pre-coated steel substrate wherein the coating including at least one titanate and at least one nanoparticle; a method for the manufacture of an assembly; a method for the manufacture of a coated steel substrate and a coated substrate substrate. It is particularly well suited for construction, shipbuilding and offshore industries.

Method for the manufacture of an assembly by submerged arc welding (SAW)

A method for the manufacture of a welded joint including the following successive steps: I. The provision of at least two metallic substrates wherein at least one metallic substrate is a steel substrate, and II. The welding of the at least two metallic substrates with a welding head while, simultaneously, applying on the at least two metallic substrates, ahead of the welding head, a welding flux including a titanate and a nanoparticulate oxide selected from the group consisting of TiO, SiO, ZrO, YO, AlO, MoO, CrO, CeO, LaOand mixtures thereof.
